Architecture-aware TARA

Definition

Architecture-aware TARA: TARA performed against a structured model of the vehicle / item architecture, not against a flat spreadsheet. Architecture-aware TARA grounds asset identification, damage-scenario coverage, and attack-path enumeration in an explicit model of ECUs, data flows, trust boundaries, and external interfaces.

Where this matters: Automotive Cybersecurity Engineering

The result is a TARA where coverage gaps and architectural change impact are visible at any time, instead of being hidden inside spreadsheet rows.
